file_temp() returns the name which can be used as a temporary file.

file_temp(pattern = "file", tmp_dir = tempdir(), ext = "")

file_temp_push(path)

file_temp_pop()

path_temp(...)

Arguments

pattern

A character vector with the non-random portion of the name.

tmp_dir

The directory the file will be created in.

ext

The file extension of the temporary file.

path

A character vector of one or more paths.

...

Additional paths appended to the temporary directory by path().

Details

file_temp_push() can be used to supply deterministic entries in the temporary file stack. This can be useful for reproducibility in like example documentation and vignettes. file_temp_pop() can be used to explicitly remove an entry from the internal stack, however generally this is done instead by calling file_temp(). path_temp() constructs a path within the session temporary directory.

Examples

path_temp()
#> /var/folders/dt/r5s12t392tb5sk181j3gs4zw0000gn/T/RtmpqBJtm7
path_temp("does-not-exist")
#> /var/folders/dt/r5s12t392tb5sk181j3gs4zw0000gn/T/RtmpqBJtm7/does-not-exist
# default just passes the arguments to `tempfile()` file_temp()
#> /tmp/filedd461c46df20
# But you can also make the results deterministic file_temp_push(letters) file_temp()
#> a
file_temp()
#> b
# Or explicitly remove values while (!is.null(file_temp_pop())) next file_temp_pop()
#> NULL
